Non-Peer ReviewedPreliminary results from the field evaluation of zero and minimum tillage seeding machines, as well as fertilizer placement techniques for zero-tillage are presented. Narrow hoe opener (Noble 2000), conventional double-disc (Haybuster 1206), as well as two modified double-disc press drills have been compared for their seeding performance and effects on crop yields in a continuous zero-till wheat test. Further, an air-seeder, a discer and a conventional hoe press-drill have been field evaluated both on cultivated fallow and stubble situations. Deep banding and side banding (approximately 2.5 cm from seed) of fertilizer using both disc and hoe press-drills have been compared to seed-placed fertilizer application
